New homes and floors in Southford
Southford is within about 2 miles of the coast. New homes near the sea put their outside mastic to work from day one, so any gaps are best picked up early. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For new homes near Shanklin station, it’s worth checking the sealant early, while snags are still fresh.

What we are called out for in Southford
Later trades and the final clean can damage fresh sealant. If it’s disturbed before curing, the joint can be left weak and it shows once the home is in use.
Any of these means the joints need attention:
- Sealant work across a run of new homes
- Beads laid onto grit and dust from the build
- Messy sealant that spoils new finishes
- Frame joints opening as the plaster dries
In and around Southford, as anywhere, good new build mastic starts with a clean, dry, properly prepared joint.
Questions to ask before booking
- Who does the work, and how experienced they are
- What product goes in the joint
- What insurance they hold
- What preparation is included

FAQs for Southford
Can you help a landlord with a rental near Shanklin station?
Yes, landlords and agents are among the people we work for, and several properties can go on one quote. You can phone 0345 464 0079 or send us an email with the details for a clear quote.
Do you cover smaller places like Southford?
Yes, we do. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.
When is the best time to reseal in a new build?
It depends on whether water is getting through. Failed seals in wet areas need doing now, but cosmetic gaps can wait for movement to slow.
Can you work from my snagging list?
Yes. We often work straight from a snagging list. We’ll go through the sealant items and agree what we’ll do.
Are you an approved applicator?
Yes. We are approved under the ARBOMaster scheme.
Is it worth trying it myself?
It depends on the job. High-level, external movement and fire-rated joints are professional jobs.
Is there a guarantee?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we will put it right.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we work across South East England, London and Scotland.

Aftercare tips
No joint lasts for ever, but care makes a real difference. Our tips:
- Get a leaking seal dealt with right away
- Put sealant faults on your snagging list early
- Keep pictures and emails about snagging items
- Wipe joints with warm soapy water
Photograph failed sealant before it’s redone and keep the builder’s replies. It helps if anything else comes up during the warranty period.
The sooner you deal with untidy or cracking sealant, the less there is to put right. Small faults turn into leaks if left.
